IntelliJ IDEA 2020.1 Help

Google App Engine for PHP

The described functionality is handled by the Google App Engine Support for PHP plugin. The plugin is no longer maintained and is incompatible with IntelliJ IDEA starting from version 2018.1.

The following is only valid when the PHP plugin is installed and enabled.

With IntelliJ IDEA, you can develop a PHP application for running in the Google PHP Runtime Environment. IntelliJ IDEA supports all the major Google App Engine for PHP development practices and provides the possibility to run and debug your applications locally before uploading them to the runtime environment.
